Embodiment

For further setting forth technological means and the effect thereof that the utility model is taked, be described in detail below in conjunction with the preferred embodiment and the accompanying drawing thereof of the utility model.

Shown in 1-4 figure; The ultra-thin keyboard of the utility model; Comprise: substrate 1, be located at film circuit board 2 on the substrate 1, several keycaps 4, the corresponding keycap 4 of being located at film circuit board 2 tops is located at elastomer (not shown) on the film circuit board 2, and corresponding keycap 4 be installed on the scissors pin 3 between keycap 4 and the substrate 1; Said substrate 1 is an aluminium sheet, and this aluminium plate thickness can be about 0.3mm (millimeter), is beneficial to the slimming design of keyboard.Keycap 4 can adopt the keycap structure of slimming design of the prior art, and film circuit board 2 adopts the film circuit board of thickness 0.15mm.

Wherein, Said scissors pin 3 comprises mutual intersection and is first framework 31 and second framework 32 of rotating pivot joint; Second framework 32 is articulated in the interior week of first framework 31, thereby forms hollow-out parts in the middle of the scissors pin 3, and elastomer is arranged in this hollow-out parts and is fixed on the film circuit board 2.First framework 31 comprises first bottom bar 311, relative with first bottom bar 311 first push rod 312, and is connected relative two first side levers 313 of first bottom bar 311 and first push rod 312; Second framework 32 also comprise second bottom bar 321, relative with second bottom bar 321 second push rod 322, and relative two second side levers, 323, the second frameworks 32 that are connected second bottom bar 321 and second push rod 322 two first side levers 313 through its two second side lever 323 and first framework 31 turn pivot joint.First bottom bar 311 of first framework 31 and the two opposite outer of first push rod 312 are equipped with fixed axis 314,315; Second bottom bar 321 of second framework 32 and the two opposite outer of second push rod 322 are equipped with fixed axis 324,325 equally; Corresponding fixed axis 314,324 is provided with hook sheet 111,112 on the substrate 1; Hook sheet 111,112 relative substrates 1 upwards bending are provided with; Corresponding fixed axis 315,325 is provided with draw-in groove (not shown) on keycap 4 bottom surfaces, and first framework 31 cooperates with substrate 1 hook sheet 111,112 respectively with the fixed axis 314,324 of second framework, 32 first bottom bars 311, second bottom bar 321, and its first push rod 312, second push rod, 322 fixed axis 315,325 cooperate with keycap 4 draw-in grooves respectively; Thereby scissors pin 3 is installed between substrate 1 and the keycap 4, realizes moving up and down of keycap 4.

Said scissors pin 3 is for cooperating the scissors pin of keycap 4 isostructural slimming designs; Specifically; First push rod, 311 lower surfaces of scissors pin 3 first frameworks 31 convex with rib 310; Rib 310 can be first bottom bar 311 and is convexly equipped with formation downwards, in the present embodiment, respectively is convexly equipped with a rib 310 on the opposite end of first framework, 31 first bottom bars, 311 lower surfaces.Said rib 310 carries out attenuate and widens setting, and the width of rib 310 is greater than the width of first bottom bar 311, and the thickness of rib 310 is not more than the thickness of substrate 1.Corresponding rib 310 offers slot part 11 on the substrate 1, and after scissors pin 3 was installed, rib 310 was embedded in the slot part 11, has improved the installation strength of scissors pin 3.Slot part 11 and hook sheet 111,112 on film circuit board 2 counterpart substrates 1 are provided with through hole 21, the fixed axis 315,325 of scissors pin 3 and rib 310 pass film circuit board 2 respectively with the hook sheet 111,112 and slot part 11 matching and fixing of substrate 1.Substrate 1 for 0.3mm thickness; The thickness of rib 310 makes when rib 310 is entrenched in the slot part 11 that to be not more than the Thickness Design of 0.3mm its bottom can not exceed substrate 1; Thereby reduced the setting height(from bottom) of scissors pin 3, effectively reduced the thickness of integral keyboard.

In addition; Two first side levers 313 of scissors pin 3 first frameworks 31 can be through suitably thickening processing; The thickness in first bottom bar 311 of first framework 31 and first push rod 312 is big to make its thickness; And corresponding two first side levers 313 are provided with fluting 22 on film circuit board 2, and fluting 22 is communicated with through hole 21, after the scissors pin 3 after the assembling presses down; Two first side levers, 313 axial components of first framework 31 are contained in the fluting 22, further improve the intensity of scissors pin 3 and do not influence the slimming and the package assembly stroke of keyboard.Therefore, the utility model can improve scissors pin 3 when keycap 4, substrate 1 and the 3 isostructural slimmings of scissors pin are provided with, and the intensity of scissors pin 3 is better when reaching slimming, and is more durable.

The ultra-thin keyboard of the utility model, when keycap 4 was applied pressing force, keycap 4 moved downward; Through elastomer conflict film circuit board 2, thereby form circuit turn-on, realize keyboard operation; Because through ultrathin design, the stroke that keycap 4 presses down shortens, operate faster and reaction soon.

In sum; The ultra-thin keyboard of the utility model, swift to operate, it is through improving the scissors pin; The rib of the scissors pin after the assembling does not exceed substrate; When effectively reducing the thickness of keyboard, improve the installation strength of scissors pin, fully satisfy people to keyboard slimming and more durable requirement.

The above; For the person of ordinary skill of the art; Can make other various corresponding changes and distortion according to the technical scheme and the technical conceive of the utility model, and all these changes and distortion all should belong to the protection range of the utility model claim.
